T1235H-8G-TR

Triacs Overview

The T1235H-8G-TR is a bidirectional triac from STMicroelectronics, rated for 12 A RMS current and 800 V blocking voltage. It operates with a maximum junction temperature of 150 °C and supports three triggering quadrants. The device features a peak on-state voltage of 1.55 V, a maximum holding current of 35 mA, and a surge current rating of 126 A. Packaged in D2PAK (TO-263) for surface mount applications, it utilizes Snubberless technology to ensure robust dynamic turn-off commutation and high noise immunity.

Triacs Feature Summary

• High-temperature operation capability up to 150 °C junction temperature
• Snubberless design eliminates the need for external RC snubber circuits
• Enhanced thermal management suitable for compact SMD designs

Triacs Applications

• Control of universal motors in home appliances
• Heater control systems
• Industrial control units requiring inductive load switching

Triacs Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm RoHS compliance status via official datasheets or manufacturer documentation before integration. Ensure the supplier provides valid traceability records for the STMicroelectronics brand component.

Triacs Selection Notes

Select this component for applications requiring high commutation capability without snubber networks. Verify that the gate trigger current requirements align with the driving circuit capabilities. Consider the D2PAK package dimensions for PCB layout constraints and thermal dissipation needs.

Triacs Part Context

This part belongs to the H-Series of high-temperature triacs designed for demanding AC load switching environments. It complements other variants like the T1235H-8I and T1235H-8T, offering surface mount convenience while maintaining the robust electrical characteristics of the family.

Triacs Replacement Considerations

Direct substitutes within the same series include T1235H-8G (tube packaging) and T1235H-8I (through-hole). Cross-package replacements require verifying pinout compatibility and thermal resistance differences.
